INTERNAL COLLAR CAN original Filed Nov. 15. 1922 llrlfll l Patented July l5, 1930 UNITED STATES' PATENT erstes JOHN M. YOUNG, OF BROOKLYN, NEW YORK, ASSIGNOR TO AMERICAN CAN COMPANY,

OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY i INTERNAL-COLLAR CAN Application led November 15, 1922, Serial No. 601,041. Renewed October 12, 1929.

My invention relates in general to .hermetic containers adapted to be opened by severing the body material beneath the top as by means of a tearing strip,` and particularly to the provision" of an internal collar, or neck member, in such a can extending across thev line of severance and frictionally secured to the body with such tightness as to provide a liquid-tight seal.

In accordance with my invention, the tearing strip is set off by score lines, which, for the purpose of facilitating the tearing action, are formed in the interior of the can body. Since in forming these lines the tinned surface of the metal is broken, ex

posing the iron, or black metal which is vulnerable tothe action of acid contents of the can, it is desirable that the supplementary wall part, or collar, serve to prevent the access of liquid to said lines. The present invention, therefore, contemplates the provision of a collar arranged within the can body in such manner as to effectively seal the score lines and adjacent areas from the contents, the can body being formed in such manner as to best co-operate with the collar to attain this result.

A further object of the invention is the provision of an interior collar can of this character in which the score lines are formed quite near the top and the innerl band extends up slightly above the uppermost score lines, so that the top may be readily removed after being torn away.

A further result obtained by the liquidtight seal is the prevention of spilling of the contents as the tearing strip is being re.

moved.

Other objects and advantages of the invention will be apparent as it is better understood from the following descriptioi1,which, taken in connection 'with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings,

Figure l is a side elevation, partially in section, of a tearing strip can in which my invention is embodied of prior to the positioning of the inner collar and the seaming of an end to the body;

are formed on the inner side ofthe body wall so that when the strip is wound outwardly upon the key which engages a tongue 17, the fracture will'be continuous and commenced from Within, thus facilitating the tearing away of the strip. It will also be noted that these parallel score lines" are arranged near the top of the can body, this being for a reason to be hereinafter stated. Diagonal score lines 18 are also provided upon this strip to "5 direct the line of tear back to the lines 15 and 16, in case there should be a tendency to tear inwardly therefrom. An interior collar 19 is provided in the upper part of the can, completely covering the scoring and the area adjacent thereto. Said collar is of such diameter as to t tightly against the inner surface of the can body and, in this connec- I tion, it is pointed out that said, body is formed with an external side seam 2l, and a seam 22, joining the ends of the collar, is oppositely formed so that the body and collar present opposed smooth surfaces. This close lfrictional fit provides a seal which prevents access of the liquid contents of the can to the score lines 15 and 16. This seal also prevents the spilling o f the contents as the tearing Vstrip is being oved. l It will be noted that the side seam 2l is a lock seam, excepting in the area of thetearing strip where 4the metal is merely lapped to permit ready tearing away of said strip.

The adaptation of my invention herein shown is particularly suited for what is known as packers line cans, which contain fruit and other substances having an acid content. With this type of can, it is manifest that the contents must be completely removed upon opening and that the severed top normally may be thrown away, so that a temporary closure will not be required. Furthermore, it is desirable that the top be read- 'ily removable after the tearingl away of the strip 14. I, therefore, in the present instance,

locate the score lines close to the tp of the body with the collar 19 extending onlyslightly thereabove, as heretofore stated. `With this construction, the severed top may be readil lifted and the short flange thereon, resultlng from the location of the score lines, is not material, since there will be no. necessity for further use of said top.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it Will be apparent that various chan es may be made in the form, construction an arrangement of the'parts, without departing froml the spirit and scope of the invention, or sac-- ricing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim: 1 l. A can,` comprising a body continuous in one piece from top to bottom having a top double-seamed and secured thereto. and adapted to be severed on a line beneath said top, and a separate neck member within the body and secured thereto and extending above and below theline of severance,said body having a side seam formed on the exterior of the can and having a flush inner surface adapted to be tightly engaged by said.

neck member to form a liquid-tight seal.

2. A can, comprisin a body having a top secured thereto, said ody having internal scoring adapted to permit severance beneath said top, and a separate neck member `arranged within the body and covering ,said scoring, said member and said body having oppositely disposed side seams and presenting smooth contact surfaces permitting of tight frictional fit and forming a liquid-tight seal between said member and body.
